Description
Technical field
The present invention relates to a kind of heating device, specially a kind of extruding die holder heating device.
Background technology
Metal hot extruding die seat is free of heating mode at present, when preheated mold is on cold die holder, mold
It will decline with the temperature of die holder contact position, the downside temperature of rip fence is less than upside, this will lead to mold in extrusion process
Metal fluidity on the lower be worse than upside, by cause squeeze product size and performance it is uneven.Novel die holder preheating
Device to avoid the above problem, can realize that the flow velocity of product, size, performance are more uniform, be particularly suitable for porous mold extruding
It is squeezed with high-precision.
Invention content
Purpose of the present invention is to realize the preheating of die holder, to ensure mold temperature uniformity and extruded product it is uniform
Property.
The following technical solution taken to realize the present invention：
A kind of extruding die holder heating device, which is characterized in that
The heating device includes die holder, temperature controller, thermocouple, heating element, cover board；
The die holder is in the structure of upper end opening, and centre opens up a step-like U-shaped straight slot, and the mold and die-cushion matching are placed on
In U-lag, the mold is placed on the front end of die-cushion and is supported by die-cushion；The die holder front end face offers another U-lag,
The pilot hole being inserted into for heating element is provided in the U-lag, the heating element includes multiple heating rods and adds multiple
The electric wire of hot pin connection,
The electric wire leads to die holder side by U-type groove and is connected with temperature controller；
Temperature controller periodically reads thermocouple measured temperature, and the temperature for controlling die holder compares the measured value in setting range
It disconnects heating element switch when higher than set temperature with the difference of the setting value of input temperature controller and stops heating, when less than setting
When constant temperature is spent, heating element switch is opened, setting value is allowed to warm to；
One non through hole is set by the temperature controller, thermocouple is installed in the non through hole, the thermocouple passes through with temperature controller
Electric wire connects.
After the heating element is inserted into the aperture in U-lag, it is enclosed in inside die holder front end by cover board；
The die holder top has stepped bulge-structure.
Further improvement of these options, heating element is using embedded design, U-shaped arrangement mode or the side of being connected in parallel
Formula.
Further improvement of these options, temperature controller carry out temperature control using PLD Kick type temperature controllers.
Further improvement of these options, thermocouple are installed with heating element Relative vertical, are located at heating element half
At the U-lag bottom of depth.
The beneficial effects of the present invention are：
The temperature of mold is more uniform when the present apparatus can be such that extruding produces, and realizes that the flow velocity of product, size, performance are more uniform,
Porous mold is particularly suitable for squeeze and squeeze in high precision.
The present apparatus has heating effect good, and can power off in time, the good feature of heat insulation effect.
Description of the drawings
Fig. 1 is exploded view.
Fig. 2 is the Novel heating die holder figure assembled.
Fig. 3 is Novel heating die holder using renderings.
Specific implementation mode
With reference to specific drawings and examples, the invention will be further described.
As shown in Figs. 1-3：A kind of extruding die holder heating device, which is characterized in that
The heating device includes die holder 3, temperature controller 7, thermocouple 6, heating element 4, cover board 5；
The die holder is in the structure of upper end opening, and centre opens up a step-like U-shaped straight slot 3.1, and the mold 1 and die-cushion 2 match
It is placed in U-lag 3.1, the mold is placed on the front end of die-cushion and is supported by die-cushion；The die holder front end face offers
Another U-lag 3.2 is provided with the pilot hole 3.3 being inserted into for heating element 4 in the U-lag, and the heating element includes multiple
The electric wire 4.2 that heating rod 4.1 is connected with by multiple heating rods,
The electric wire leads to die holder side by U-type groove 3.2 and is connected with temperature controller 7；
One non through hole 8 is set by the temperature controller, thermocouple 6 is installed in the non through hole 8, the thermocouple is logical with temperature controller
Cross electric wire connection.
The thermocouple is installed with heating element Relative vertical, is located at the U-lag bottom of heating element half depth.Heat
Galvanic couple, the temperature for periodically measuring die holder.
Temperature controller periodically reads thermocouple measured temperature, and the temperature for controlling die holder compares the survey in setting range
The difference of definite value and the setting value of input temperature controller disconnects heating element switch and stops heating, when low when higher than set temperature
When set temperature, heating element switch is opened, setting value is allowed to warm to.
After the heating element is inserted into the aperture 3.3 in U-lag, it is enclosed in inside die holder front end by cover board 5；
The die holder top has stepped bulge-structure 3.4.
Further improvement of these options, heating element 4 is using embedded design, U-shaped arrangement mode or is connected in parallel
Mode.
Further improvement of these options, temperature controller carry out temperature control using PLD Kick type temperature controllers.
Further improvement of these options, temperature controller carry out temperature control using PLD Kick type temperature controllers.
In Fig. 2, heating die holder can be used after assembling.Button inputs desired heating temperature, heating in temperature controller
Die holder begins heat to setting value, stops heating, its displays temperature is consistent with set temperature at this time.When temperature controller periodic reading
When the displays temperature that thermocouple is surveyed is less than set temperature, after and begin to warm up, until displays temperature again and set temperature
Heating is unanimously just disconnected, is so recycled.
Fig. 3 is after heating die holder displays temperature to setting value, you can is packed into preheated mold die-cushion, starts to squeeze life
Production.
It should be noted last that the above specific implementation mode is merely illustrative of the technical solution of the present invention and unrestricted,
Although being described the invention in detail with reference to example, it will be understood by those of ordinary skill in the art that, it can be to the present invention
